Categorical AI phenomenology: A first-person approach
Robert Prentner
TL;DR
The paper addresses how to study whether computers can have subjective experience by treating consciousness as experience enacted through an agent’s interface with the world. It proposes Q-networks and categorical structures as a minimal mathematical framework for modeling first-person phenomenology and relational experiential patterns.
Problem
Research on machine consciousness must integrate a first-person perspective with conventional third-person science to explain how information-processing physical systems could have subjective experience.
Method
The paper models first-person structures of experience using Q-networks and derives categorical structures from relational data rather than privileging a particular substrate.
Results
The framework characterizes artificial phenomenology through relational structures, including experiential unities and recurrent experiential loops captured by categorical invariants.
Takeaways & Limitations
Artificial consciousness is approached as a question of the relational structures computational systems exhibit, rather than an intrinsic or undefined property of the systems themselves.
Takeaways & Limitations
The paper does not address whether agency itself rules out machine consciousness, leaving that discussion outside its scope.
Abstract
from arXiv · showhide
This paper develops a phenomenology-first approach to artificial consciousness by reframing consciousness as the subjective experience enacted through an agent's interface with the world. We shift the methodological focus to first-person structures, modeled mathematically by categories derived from Q-networks to capture actions and phenomenological invariants. In this framework, Q-networks are conceptualized as relational interfaces encoding agent-world interaction, analogous to how the dynamical states of a computer depend on its sensory inputs, previous states, and actions. Our work provides a rigorous framework for interface consciousness to describe computational systems that embed information-processing into phenomenological structure. The approach aligns with 4E approaches to cognition by emphasizing enactive, embedded, and extended dimensions of experience. The paper thus offers a principled, relational, and phenomenological account of artificial phenomenology grounded in categorical mathematics.
1. First-person computation
The paper frames machine consciousness as subjective experience enacted through an agent’s interface with the world and proposes studying it from a first-person perspective. It introduces Q-networks and category theory as a mathematical framework for modeling relational structures of experience.
- First-person computation: Machine consciousness is approached as subjective experience enacted through an agent’s interface with the world.The paper focuses on interfaces that organize computational processes according to phenomenological principles.
- First-person computation: A phenomenology-first methodology begins with how appearances are given from the first-person perspective rather than relying exclusively on third-person data.The paper motivates this inversion by noting challenges in constructing a meaningful science of consciousness from brain scans alone.
- First-person computation: The framework aims to integrate first-person studies with contemporary models of computation through a mathematical treatment extending beyond descriptive Husserlian phenomenology.The authors present category theory as an abstract framework already applied to theoretical computer science and programming.
- First-person computation: Category theory is chosen because the paper treats phenomenology as relational, including relations between subjective acts and objects and between potential and actual experiences.The approach is distinguished from treating consciousness as purely descriptive introspection.
- First-person computation: The paper introduces Q-networks as a minimal formalism for modeling first-person structures of experience and artificial phenomenology.It extends earlier work on phenomenal spaces and proposes deriving categorical structures from Q-networks.
2. Categorical phenomenology
Categorical phenomenology treats experience as a relational structure linking actual and possible experiential states, then represents those relations mathematically with Q-networks and categorical constructions. The framework aims to remain minimal, general, and applicable across biological and artificial systems.
- Relational foundations: Phenomenology is relational because it analyzes both relations among experiences and relations between actual and possible experiences.Possible experiential trajectories connect potential experiences and define shared relational properties.
- Modeling requirements: The framework begins with few explicit assumptions while remaining general, universal, and metaphysically neutral across different kinds of entities.The authors explicitly include humans, animals, AIs, and aliens within its intended scope.
- Structure-first approach: A structure-first approach derives phenomenological objects from relational data rather than privileging a biological or artificial substrate.The proposed objects may arise from cliques, trajectories, networks of sensory states, brain states, or computer memory states.
- Categorical organization: Category theory organizes objects, morphisms, composition, and identity laws, while allowing objects to function as interfaces for composing morphisms.Phenomenological objects are treated as structures, and morphisms represent relations between them.
- Q-networks: Q-networks encode relations among potential experiential states, with kernels that may be probabilistic, weighted, or binary and can be indexed by actions.In the deterministic finite-state case, kernels are binary matrices whose rows contain exactly one 1 and states have outgoing transitions.
X id not
The paper derives categorical structures from Q-networks to represent phenomenological invariants, actions, and unifying structures. These constructions connect relational patterns in experience with categorical mappings and physical data.
- Categorical framework: Category theory is used to derive structures from Q-networks rather than treating the Q-network itself as a category.In the toy model, objects are cliques and morphisms are inclusions, producing a poset-like category.
- Invariants: The framework represents phenomenological invariants through functorial correspondences that preserve structure across thresholds.Persistent homology can summarize Q-network-derived structures using Betti numbers such as β0.
- Actions: Actions are modeled by functors, with sequential functors representing sequential transformations of experiential structure.The framework includes attention-related actions such as loosening and sharpening, while composition rules can be additive or maximum-based.
- Universal structures: Colimits unify relational patterns into minimal objects through which the relevant mappings factor.The paper interprets this construction as a meeting point for perception–action loops and illustrates it with categorical diagrams.
- Phenomenological unification: The categorical construction is intended to represent mental properties and relate them functorially to physical data after embedding them into Q-networks.This extends the paper’s relational approach from state transitions toward phenomenological structure.
3. Interface consciousness and a concrete toy model
The paper frames consciousness as subjective experience enacted through agent-world interfaces and illustrates this framework with a computational toy model linking third-person data to categorical and topological structures.
- Interface consciousness: Q-networks provide relational scaffolding for interface consciousness by encoding relations between an agent’s states.The approach treats consciousness as enacted through interfaces rather than as an inner theater.
- Concrete toy model: The toy model embeds third-person data into a phenomenal space, organizes the resulting states into Q-networks, and analyzes them categorically and topologically.It uses synthetic time-series data and demonstrates the proposed phenomenological hierarchy from data to embeddings, networks, categories, and invariants.
- Categorification and invariants: Similarity relations are converted into simplicial complexes through clique constructions, while persistent homology summarizes their structural invariants across thresholds.Temporal scaffolding is omitted for this categorical analysis, and arbitrary categorical constructions are avoided because compositional morphisms could introduce spurious homological features.
- Summary and limitations: The model’s apparent links between Betti-number crossings and qualitative regime shifts are heuristic patterns from the toy example, not general mathematical theorems.The authors distinguish persistent homology’s role in capturing relational shape from category theory’s role in describing transformations between such shapes.
- Categorification and invariants: β1 peaks near threshold ≈0.65, marking the toy model’s maximal relational tension between unity, recurrent motifs, and remaining diversity.β1 is interpreted as experiential loops; at lower thresholds, these loops decline as connectivity becomes more globally integrated.
- Summary and limitations: The synthetic toy model remains limited because it does not fully represent phenomenological themes such as self, time, and unity.The paper suggests future extensions, including self/world partitions and reintroduced temporal adjacency.
4. More complex phenomenological properties
The paper extends Q-network analysis from minimal relational organization toward phenomenological properties such as self-consciousness, time-consciousness, and process unity. Applied category theory represents these properties through types, processes, compositions, and equivalences.
- Q-networks integrate information-processing data with a first-person perspective through invariants, action-dependency, and structural unification.
- Minimal Q-network organization is a structural precondition for intentional consciousness, which requires additional constraints.
- Time-consciousness: Time-consciousness concerns the organization of experience, rather than merely labeling experiences as past, present, or future.
- Process unity: Applied category theory treats Q-network-derived categorical structures as types and their transformations as processes.
- Process unity: Sequential and parallel process compositions can be represented by string diagrams, whose equivalences express constraints related to consciousness unity.
- Process unity: Intentional consciousness is unified when its string-diagram representation cannot be rewritten into an equivalent disconnected representation.
5. Conclusions and outlook
The paper proposes categorical phenomenology as a framework for computational systems, using Q-networks and phenomenological constraints to model first-person interfaces. It recommends evaluating the relational richness of such interfaces while acknowledging unresolved empirical testing boundaries.
- The paper proposes a phenomenological framework in which category theory represents phenomenology’s doubly relational nature and Q-network-derived categorical objects represent central phenomenological notions.
- Category theory is presented as a precise, high-level link for interpreting and designing Q-networks organized around phenomenological concepts.
- Testing the framework is difficult because consciousness is not third-personally observable and machines may produce sophisticated behavior without consciousness.
- The proposal treats computational processes as subjectively enabling when phenomenological concepts constrain them and jointly determine an agent’s world interface.
- Relational richness can be evaluated through structural unification and action-indexed reorganization of categorical structures.
- Future work should apply Q-network analysis to molecular, cellular, neuronal, and digital third-person data.
